Brief Summary

Cachexia, a condition of severe malnutrition, negative nitrogen balance, muscle wasting, weight loss, and anorexia, is a frequent affecting more than 80% of patients in advanced cancer disease causing a high burden on patients and their families. Nutritional, pharmacological, and behavioural interventions for cancer-related ACS and associated symptoms have, despite the importance for cancer care, limited effect on only a minority of patients. New strategies are required.

Ghrelin, a 28 amino acid peptide discovered in 1999, is predominantly secreted by gastric endocrine cells and is an endogenous ligand for the growth hormone secretagogue (GHS) receptor. When administered peripherally it stimulates growth hormone secretion, food intake, triggers a positive energy balance, produces weight gain through a central mechanism involving hypothalamic neuropeptides and has anti-inflammatory effects. A recently completed trial on intravenous ghrelin in advanced cancer patients with ACS reports good tolerability and safety of single intravenous application of 2 and 8μg/kg Ghrelin.

Given the facts that ACS is a major burden in patients suffering advanced cancer disease and ghrelin is a major signal for stimulating food intake, promoting positive energy balance and weight gain and may have anti-inflammatory effect it remains to be determined whether the administration of ghrelin will have a positive clinical effect on cancer anorexia/ cachexia syndrome ACS. The next logical clinical development step is a proper dose-finding study of twice daily subcutaneous administration and proof-of-concept of main outcomes.

Group Type: EXPERIMENTAL

ghrelin

Intervention Type: DRUG

As starting dose the investigators choose a dose level which was shown in our last study to be safe in human beings, i.e. 8μg/kg intravenously. With an assumed bioavailability of 25% of subcutaneously administered ghrelin the corresponding dose for dose level 1 is therefore 32 μg/kg. In the first 4 dose levels for each subsequent dose level the dose is increased by 50% compared to the previous one, from the 5th dose level onwards the increase is 25%: Dose level 1 = 32 μg/kg Dose level 2 = 48 μg/kg Dose level 3 = 72 μg/kg Dose level 4 = 108 μg/kg Dose level 5 = 135 μg/kg Dose level 6 = 169 μg/kg Dose level 7 = 211 μg/kg The investigators define the maximum tolerable dose as 20mg ghrelin (equivalent to 5ml) for reasons of the high drug volume to be administered subcutaneously.

• No other trial: Patient is not or was not participating in any other clinical trial within 28 before visit 2.
• Women of childbearing potential: A negative pregnancy test & effective contraception are mandatory in child-bearing age.
• Men agree not to father a child (i.e. use adequate birth control if sexually active) during participation in the trial.
• Cognition: Presence of a normal level of consciousness (mandatory is a normal abbreviated screening mini-mental test or a common mini-mental ≥ 27/30; in elderly patients age ≥ 65 years or patients with low education a mini mental status of ≥25/30 points will be considered adequate).
• Consent: The patient has voluntarily signed and dated an independent Ethics Committee (IEC) approved consent prior to any study-specific procedures.
• Gastrectomy: Patients with history of gastrectomy are eligible.

Exclusion:

• Questionnaires: Any psychiatric disorder, alcohol and illicit drug abuser language problem that would prevent the patient from filling in the questionnaires adequately.
• Patient with a history of psychiatric diagnosis of depression or clinical diagnosis of depression as determined by the treating physician or Hospital Anxiety Depression Scale total score of 13 or greater.

• Known hypersensitivity to ghrelin.
• Known infection with HIV or a viral hepatitis
• Patients with known myeloid malignancy or tumours having bone marrow involvement
• Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.
• Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.
